A new tour billed as "Drake vs. Lil' Wayne" is one of the more irresistible concepts of the summer.

Hip-hop stars Drake and Lil' Wayne made Indianapolis the second stop of the tour on Saturday, when a friendly competition unfolded between two acts on the same label -- Lil' Wayne's Young Money.

The stakes in this battle? The title of "Greatest Rapper in the World," according to the participants.

As a bonus, "Drake vs. Lil' Wayne" supplied a comedic roast for the estimated audience of 20,000 at Klipsch. We saw Lil' Wayne flat on his back onstage, pretending to nap during one of Drake's ballads. Elsewhere, Drake fired off a line based on Lil' Wayne's up-and-down chart performance of late, advising him to perform some of his hits from "15 years ago."

At first, the night was structured to resemble a boxing match. The initial rounds featured each rapper performing three to four songs before yielding the stage to the other. Somewhere in the middle, the format devolved to allow Drake extended time in the spotlight. Then Drake and Lil' Wayne decided to trade excerpts of hit songs in rapid-fire fashion.

Drake is free to mock Lil' Wayne for his longevity, as if it were a bad thing. But Weezy is a time-tested live performer, and he's been killing it since he played Market Square Arena in the late 1990s.

At his best, Wayne is athletic, crouched and coiled while plowing through rhymes. He was especially fierce during a rendition of "Sky's the Limit": "If you want trouble, I want the same thing."

Drake, meanwhile, is a tiresome lyricist who seems content to be the least humble act around. Thanks to 2011 hit "Headlines," we know his "money over everything" philosophy and he drinks every night because he drinks to his accomplishments. Fans will remember his overhead "flight" from the stage to the pavilion's soundboard, but Drake is overdue when it comes to delivering substance in his work.

A winner was announced near the end of the show, when Lil' Wayne's name appeared on a video screen -- giving him a 2-0 record on the young tour.

I agree with the verdict, and the competition could be boiled down to two signature songs.

Lil' Wayne had "A Milli," his mind-bending, politically incorrect hit from 2008. While the song is six years old, it sounded exceedingly fresh at Klipsch.

Drake countered with "Started from the Bottom," a song that's saturated pop culture. But, like so much of Drake's repertoire, this is a song that's all hook and no lyrical heat.
